Description

Technical Field

[0001] This application relates to the field of rapid surface treatment of gas storage cylinders, and in particular to a device for rapid surface treatment of aluminum alloy gas storage cylinders. Background Technology

[0002] Aluminum alloy gas cylinders are widely used in automobiles, construction machinery, rail transportation and other fields due to their advantages such as light weight, corrosion resistance and high strength. During the production process of aluminum alloy gas cylinders, their surface is prone to producing microburrs and oxide films due to processing steps such as casting, stamping and cutting. Therefore, gas cylinders need to be treated with equipment to remove microburrs and oxide films during the production process to improve the appearance of the gas cylinder surface.

[0003] Most existing mechanical processing equipment uses a single centrifugal motion to drive grinding, which results in insufficient friction between the air storage cylinder and the grinding material. This makes it easy for some parts of the air storage cylinder to be missed during grinding, thus reducing the processing quality of the air storage cylinder. In addition, only a small number of air storage cylinders can be processed at a time, reducing the processing efficiency of the air storage cylinder. Utility Model Content

[0004] To address the issues of insufficient friction leading to leakage during single centrifugal motion and the reduced processing efficiency due to the limited capacity to process only a small number of gas cylinders at a time, this application provides a device for rapid surface treatment of aluminum alloy gas cylinders.

[0005] The device for rapid surface treatment of aluminum alloy gas cylinders provided in this application adopts the following technical solution: A device for rapid surface treatment of aluminum alloy gas storage cylinders includes a grinding barrel, a turntable for driving the grinding barrel to revolve around a central point is provided on one side of the surface of the grinding barrel, and a transmission shaft for driving the grinding barrel to reverse rotation is provided on the side of the surface of the grinding barrel near the turntable. A drive mechanism for driving the turntable to revolve is provided on one side of the surface of the grinding barrel, and a transmission component for transmitting the power of the drive mechanism to rotate the transmission shaft is provided on one side of the surface of the turntable.

[0006] By adopting the above technical solution, the turntable is driven to rotate by the drive mechanism, which in turn drives the transmission shaft to rotate. Under the action of the transmission components, the grinding barrel rotates in the opposite direction at the same speed while being driven to rotate by the turntable. This causes the air storage cylinder and the abrasive in the grinding barrel to generate strong friction under the action of dual centrifugal force, thereby improving the processing effect on the air storage cylinder.

[0007] Preferably, the drive mechanism includes a motor disposed on one side of the turntable surface, the output end of the motor is provided with a rotating shaft disposed on one side of the turntable surface, and the end of the rotating shaft away from the motor is provided with a main shaft.

[0008] By adopting the above technical solution, the motor provides power to the rotating shaft, so that the output end of the motor drives the rotating shaft to rotate, the rotating shaft drives the turntable to rotate, the turntable drives the transmission shaft to rotate, and the transmission shaft drives the grinding barrel to rotate, so that the air storage cylinder and abrasive in the grinding barrel are ground under the action of single centrifugal force.

[0009] Preferably, a plurality of connecting shafts arranged in a ring around the main shaft are provided on one side of the surface of the turntable. A limiting disk is provided at the end of the connecting shaft away from the turntable. A limiting shaft is provided on one side of the surface of the limiting disk. A limiting seat is provided at the end of the limiting shaft away from the limiting disk.

[0010] By adopting the above technical solution, the grinding barrel is limited by the limiting plate, limiting shaft and limiting seat during the rotation process, so as to ensure the stability of the grinding barrel during the rotation process.

[0011] Preferably, the transmission assembly includes a planetary gear ring disposed on one side of the turntable surface and planetary gears disposed at the end of the transmission shaft away from the grinding barrel. The planetary gears are arranged in a ring around the turntable on one side of the turntable surface, and the planetary gear ring meshes with the planetary gears for transmission.

[0012] By adopting the above technical solution, the turntable drives the planetary gears to rotate during rotation. The planetary gears mesh with the planetary gear ring, so that the rotation direction of the planetary gears is opposite to the rotation direction of the turntable, thereby allowing the air storage cylinder and abrasive in the grinding barrel to be ground under the action of dual centrifugal force.

[0013] Preferably, the grinding barrel is provided with barrel lids on both sides of its surface, and a sealing frame for sealing between the barrel lid and the grinding barrel is provided on the side of the barrel lid near the surface of the grinding barrel. A positioning component for positioning the grinding barrel and the barrel lid together is provided between the grinding barrel and the barrel lid.

[0014] By adopting the above technical solution, the barrel lid is fixed to both sides of the surface of the grinding barrel by the positioning component, and the sealing frame is used to seal the barrel lid and the grinding barrel, preventing the grinding agent inside the grinding barrel from leaking out.

[0015] Preferably, the positioning assembly includes multiple positioning seats disposed on both sides of the surface of the grinding barrel and multiple positioning blocks disposed on both sides of the surface of the barrel cover. A drive frame is disposed on one side of the surface of the positioning seat, and a positioning rod disposed inside the positioning seat is disposed at one end of the drive frame near the positioning block. A rod groove is opened on one side of the surface of the positioning block to match the end of the positioning rod away from the drive frame.

[0016] By adopting the above technical solution, when one side of the barrel lid surface abuts against one side of the grinding barrel surface, the positioning block on the barrel lid surface is inserted into the interior of the positioning seat, and after insertion, the positioning block is fixed inside the positioning seat by the positioning rod, thereby fixing the grinding barrel and the barrel lid together.

[0017] Preferably, limiting plates are provided on both sides of the surface of the positioning rod and disposed inside the positioning seat.

[0018] By adopting the above technical solution, the positioning rod is limited by the limiting plate to prevent the positioning rod from shifting or falling out of the positioning seat during movement.

[0019] Preferably, a spring is provided on the side of the limiting plate near the drive frame, which is located inside the positioning seat.

[0020] By adopting the above technical solution, under the elastic force of the spring, the positioning rod always fixes the positioning block inside the positioning seat when it is not subjected to external force, so that the barrel cover and the grinding barrel can remain stable after they are fixed.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The drive mechanism drives the turntable to revolve, while the transmission component causes the grinding barrel to rotate in the opposite direction on top of the revolution. This causes the air reservoir and the abrasive inside the grinding barrel to generate strong friction under the action of dual centrifugal force. This dual motion effectively removes the tiny burrs and oxide film on the surface of the air reservoir, achieving a mirror-like finish and avoiding problems such as missed grinding and color difference, thus improving the processing quality of the air reservoir. At the same time, the interior of the grinding barrel is divided into two independent grinding spaces by a partition, and the turntable can drive multiple grinding barrels to operate in parallel, realizing multi-station synchronous processing and significantly improving the processing efficiency of the air reservoir's appearance.

[0022] 2. The grinding barrel and the lid are fixed by a positioning component. The positioning rod is stably engaged with the positioning block under the action of the spring force, preventing the lid from being dislodged by the air storage cylinder when the grinding barrel rotates. At the same time, the sealing frame can prevent the grinding agent inside the grinding barrel from leaking out, reducing grinding agent loss. The overall structure ensures operational safety and equipment stability. Attached Figure Description

[0025] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.

[0026] This application discloses a device for rapid surface treatment of aluminum alloy gas storage cylinders.

[0027] Reference Figure 1 A device for rapid surface treatment of aluminum alloy gas storage tanks includes a cover 1, which is welded together from steel plates. A ventilation louver baffle is installed on the lower end face of the rear end of the cover 1, and the cover can be opened and closed for convenient subsequent maintenance and adjustment. The front end of the cover 1 is equipped with an openable and closable protective door. A proximity switch is installed inside the door, and the door is designed to open and close automatically. After the door is opened automatically, the device will automatically cut off the power and stop rotating to ensure operational safety. When the device is running, the door is in the closed state and cannot be opened to ensure the safety of the device during use. The machine cover 1 is fixedly connected to the inside of the frame 11, which is made of square tubing welded together. A cooling fan is installed on the top wall of the machine cover 1. A collection box 13 for collecting abrasive is inserted into one side of the surface of the machine cover 1. An electrical appliance cabinet 3 is fixedly connected to the inner wall of the machine cover 1. The electrical appliance cabinet 3 is made of cold-rolled steel plate.

[0028] Reference Figures 1-6 The inside of the machine cover 1 is equipped with a grinding barrel 2. A partition 21 is fixedly connected inside the grinding barrel 2 to separate the inside of the grinding barrel 2. The inside of the grinding barrel 2 is divided into two independent grinding spaces 22 by the partition 21. The grinding spaces 22 are used to place the air storage cylinder and the grinding agent.

[0029] It should be noted that after the gas storage cylinder is processed, the abrasive inside the grinding space 22 can be directly poured into the collection box 13 to complete the collection of the abrasive.

[0030] The grinding barrel 2 is divided into two grinding spaces 22 by the partition 21, so that the grinding barrel 2 can process multiple air storage cylinders at the same time, thereby improving the processing speed of the air storage cylinders.

[0031] Reference Figures 2-4 A turntable 4 for driving the grinding barrel 2 to revolve is provided on one side of the surface of the grinding barrel 2. A drive mechanism 5 for driving the turntable 4 to revolve is provided on one side of the surface of the grinding barrel 2. The drive mechanism 5 includes a motor 51 fixedly connected to one side of the surface of the frame 11. The output end of the motor 51 is fixedly connected to a rotating shaft 52 through a coupling. The end of the rotating shaft 52 away from the motor 51 is fixedly connected to the center of the turntable 4 near the motor 51. A main shaft 53 is fixedly connected to the center of the surface of the turntable 4 away from the motor 51. The grinding barrel 2 is arranged in a ring inside the machine cover 1 with the main shaft 53 as the center. The length of the main shaft 53 is greater than the length of the grinding barrel 2. The grinding barrel 2 is fixedly connected to a drive shaft 6 for driving the grinding barrel 2 to rotate at one end near the turntable 4. The surface of the drive shaft 6 is rotatably connected to the surface of the turntable 4 away from the motor 51 via a bearing. The bearing includes an inner ring, an outer ring, rolling elements, and a cage. The bearing is an existing and mature technology, and the principle of the bearing will not be described in detail. The outer ring of the bearing on the surface of the drive shaft 6 is fixedly connected to the surface of the turntable 4 away from the motor 51.

[0032] Motor 51 provides power to rotating shaft 52, causing the output end of motor 51 to drive rotating shaft 52 to rotate. Rotating shaft 52 drives rotating disk 4 to rotate, rotating disk 4 drives transmission shaft 6 to rotate, and transmission shaft 6 drives grinding barrel 2 to rotate. This causes friction between the air storage cylinder and the abrasive in the grinding barrel 2 under the action of single centrifugal force, so that the abrasive processes the surface of the air storage cylinder and dead corners, avoiding problems such as missed grinding and color difference.

[0033] Reference Figures 2-3Multiple connecting shafts 41 arranged in a ring around the main shaft 53 are fixedly connected to the side of the turntable 4 away from the motor 51. A limiting disk 42 is fixedly connected to the end of the connecting shaft 41 away from the turntable 4. A limiting shaft 43 is fixedly connected to one side of the surface of the limiting disk 42. A limiting seat 12 is fixedly connected to one side of the surface of the frame 11. The end of the limiting shaft 43 away from the limiting disk 42 is rotatably connected to the middle of the side of the limiting seat 12 near the limiting shaft 43 via a bearing. The outer ring of the bearing at the end of the limiting shaft 43 away from the limiting disk 42 is fixedly connected to the middle of the side of the limiting seat 12 near the limiting shaft 43.

[0034] During the rotation of the grinding barrel 2, the limiting plate 42, the limiting shaft 43 and the limiting seat 12 limit the movement, ensuring the stability of the grinding barrel 2 during rotation. At the same time, they support the grinding barrel 2 to prevent excessive weight caused by the air storage cylinder and grinding agent inside the grinding barrel 2 from affecting the normal rotation of the grinding barrel 2.

[0035] Reference Figures 2-4 A transmission assembly 7 is provided on one side of the surface of the turntable 4 to transmit power from the drive mechanism 5 to rotate the drive shaft 6. The transmission assembly 7 includes a planetary gear ring 71 disposed inside the machine cover 1. A fixing block 711 and a fixing plate 712 are fixedly connected to the outer surface of the planetary gear ring 71. The end of the fixing block 711 and the fixing plate 712 away from the planetary gear ring 71 is fixedly connected to one side of the surface of the frame 11. A planetary gear 72 is fixedly connected to the end of the drive shaft 6 away from the grinding barrel 2. The planetary gears 72 are arranged in a ring around the turntable 4 on one side of the surface of the turntable 4. The inner ring of the planetary gear ring 71 meshes with the planetary gears 72 for transmission.

[0036] It should be noted that when the turntable 4 rotates clockwise, the turntable 4 drives the drive shaft 6 to rotate clockwise. The drive shaft 6 drives the planetary gear 72 to perform circular motion around the center of the turntable 4. Through the meshing of the planetary gear ring 71 and the planetary gear 72, the drive shaft 6 rotates counterclockwise while following the clockwise rotation of the turntable 4.

[0037] As the turntable 4 drives the drive shaft 6 to rotate, the drive shaft 6 drives the planetary gear 72 to perform circular motion around the turntable 4. The drive shaft 6 meshes with the planetary gear ring 71 through the planetary gear 72, so that while the drive shaft 6 rotates with the turntable 4, the drive shaft 6 itself rotates in the opposite direction. This causes the grinding barrel 2 to be subjected to a double centrifugal force, which causes the air reservoir and the abrasive in the grinding barrel 2 to undergo strong friction under the action of the double centrifugal force. This can effectively remove the tiny burrs and surface oxide film on the surface of the air reservoir, and at the same time, make the surface of the air reservoir achieve a mirror effect, greatly improving the processing effect on the surface of the air reservoir.

[0038] Reference Figure 6The grinding barrel 2 has a lid 8 on both sides of its surface. A sealing frame 81 for sealing between the lid 8 and the grinding barrel 2 is fixedly connected to the side of the lid 8 near the surface of the grinding barrel 2. The sealing frame 81 is composed of multiple sealing strips. Sealing grooves adapted to the sealing frame 81 are opened on both sides of the surface of the grinding barrel 2 near the lid 8. The sealing grooves are in the shape of a square.

[0039] The grinding barrel 2 and the barrel cover 8 are sealed by the sealing frame 81 to prevent the grinding agent inside the grinding space 22 from leaking out and reduce the loss of grinding agent.

[0040] Reference Figures 2-10 A positioning component 9 is provided between the grinding barrel 2 and the barrel cover 8 to position the grinding barrel 2 and the barrel cover 8 together. The positioning component 9 includes multiple positioning seats 93 fixedly connected to both sides of the surface of the grinding barrel 2 and multiple positioning blocks 94 fixedly connected to both sides of the surface of the barrel cover 8. The side of the positioning seat 93 near the surface of the barrel cover 8 has a positioning groove 931 that matches the positioning block 94. The surface of the positioning block 94 abuts against the inner wall of the positioning groove 931 so that the positioning block 94 will not easily detach from the interior of the positioning groove 931. The side of the positioning seat 93 away from the positioning block 94 abuts against a drive frame 91. The surface of the drive frame 91 is E-shaped in the transverse direction. A number of positioning rods 92, equal in number to those of positioning blocks 94, are fixedly connected to one end of the drive frame 91 near the positioning block 94. The end of the positioning rod 92 furthest from the drive frame 91 is semi-circular, with the semi-circular shape pointing towards the direction in which the positioning block 94 inserts into the positioning groove 931. A sliding groove 932 is provided on the surface of the positioning seat 93 near the drive frame 91. The inner wall of the sliding groove 932 abuts against the surface of the positioning rod 92, allowing the positioning rod 92 to slide stably within the sliding groove 932. A groove is provided on one side of the surface of the positioning block 94, corresponding to the end of the positioning rod 92 furthest from the drive frame 91. The matching rod groove 941 is a semi-arc groove. The two sides of the surface of the positioning rod 92 are fixedly connected to the limiting plate 921. The inner wall of the slide groove 932 is provided with limiting grooves 933 that are adapted to the limiting plate 921. The surface of the limiting plate 921 abuts against the inner wall of the limiting groove 933, so that the limiting plate 921 can slide stably inside the limiting groove 933. A spring 922 is fixedly connected to the side of the limiting plate 921 near the drive frame 91. The side of the spring 922 away from the surface of the limiting plate 921 is fixedly connected to the top wall of the limiting groove 933.

[0041] It should be noted that: during the process of the positioning block 94 being inserted into the positioning groove 931, the positioning rod 92 can be lifted by the semi-circular surface of the positioning rod 92, causing the positioning rod 92 to move upward. After the positioning rod 92 is inserted into the rod groove 941, the positioning block 94 cannot be removed from the inside of the positioning groove 931. It can only be removed from the inside of the rod groove 941 by the force of the drive frame 91 moving away from the surface of the positioning seat 93. Only then can the positioning block 94 be removed from the inside of the positioning groove 931, thereby fixing the positioning block 94 and the positioning seat 93 together, and fixing the grinding barrel 2 and the barrel cover 8 together, so that the barrel cover 8 will not separate from the grinding barrel 2 due to the impact of the air storage cylinder during the rotation of the grinding barrel 2.

[0042] The calculation formula for spring 922 is: F=kx, where F is the external force on spring 922, unit: N, k is the spring constant of spring 922, unit: N / m, and x is the deformation of spring 922, unit: m. The elastic force of spring 922 is then calculated so that it can be used in this application.

[0043] When the surface of the barrel lid 8 abuts against the surface of the grinding barrel 2, the positioning block 94 is inserted into the positioning groove 931, the rod groove 941 and the positioning seat 93 are in a mutually facing state, and the surface of the sealing frame 81 abuts against the inner wall of the sealing groove on the surface of the grinding barrel 2.

[0044] When the barrel lid 8 is fixed on both sides of the surface of the grinding barrel 2, the positioning blocks 94 on both sides of the surface of the barrel lid 8 are inserted into the positioning grooves 931. During the process of the positioning blocks 94 being inserted into the positioning grooves 931, the positioning rod 92 is lifted, causing the positioning rod 92 to move upward. The positioning rod 92 drives the limiting plate 921 to move upward. The limiting plate 921 presses the spring 922, causing the spring 922 to deform. When the rod groove 941 on the surface of the positioning block 94 moves to be directly opposite the end of the positioning rod 92 away from the drive frame 91, the positioning rod 92 loses the lifting force from the surface of the positioning block 94, the limiting plate 921 loses power, and the spring 922 loses pressure. The spring 922 begins to recover its deformation. The limiting plate 921 moves downward by the elastic force of the spring 922 recovering its deformation, causing the limiting plate 921 to drive the positioning rod 92 to move downward, so that the positioning rod 92 is inserted into the inside of the rod groove 941. The end surface of the positioning rod 92 away from the drive frame 91 abuts against the inner wall of the rod groove 941, fixing the positioning block 94 inside the positioning seat 93, thereby fixing the barrel cover 8 on the surface of the grinding barrel 2.

[0045] When it is necessary to remove the barrel cover 8 from both sides of the surface of the grinding barrel 2, simply pull the drive frame 91 away from the positioning seat 93. The drive frame 91 will drive the positioning rod 92 away from the positioning block 94, so that the positioning rod 92 will disengage from the inside of the rod groove 941. When the positioning rod 92 is completely disengaged from the inside of the rod groove 941, the positioning rod 92 will release the limiting position of the positioning block 94, so that the positioning block 94 can be disengaged from the inside of the positioning groove 931, thus completing the disassembly between the grinding barrel 2 and the barrel cover 8.

[0046] The grinding bucket 2 is made of steel plate, and the sealing frame 81 is made of wear-resistant rubber material. The sealing effect reaches the IP65 protection standard, ensuring that the grinding agent will not leak out.

[0047] Before this application is used, the grinding barrel 2 and the barrel cover 8 are in a fixed state.

[0048] The implementation principle of the device for rapid surface treatment of aluminum alloy gas cylinders in this application embodiment is as follows: During use, the protective door of the machine cover 1 is opened, and the grinding barrel 2 is separated from the barrel cover 8 by the positioning component 9. The gas cylinder to be treated and the grinding agent are placed inside the grinding space 22. During the placement process, the grinding barrel 2 is manually rotated so that the grinding barrel 2 is in an upward tilted state, that is, the grinding space 22 is tilted upward. After the gas cylinder and the grinding agent are placed, the grinding barrel 2 and the barrel cover 8 are fixed together again by the positioning component 9. The protective door of the machine cover 1 is closed so that the grinding barrel 2 is in a fully enclosed environment.

[0049] Subsequently, the drive mechanism 5 and the transmission assembly 7 cause the drive shaft 6 to rotate in the opposite direction while following the rotation of the turntable 4. This causes the grinding barrel 2 to be subjected to a double centrifugal force, resulting in strong friction between the air reservoir and the abrasive inside the grinding barrel 2 under the action of the double centrifugal force. This allows the abrasive to process the surface of the air reservoir and dead corners, avoiding problems such as missed grinding and color difference. It effectively removes the tiny burrs and surface oxide film on the surface of the air reservoir, while also enabling the surface of the air reservoir to achieve a mirror effect, greatly improving the processing effect on the surface of the air reservoir.

[0050] Meanwhile, the turntable 4 can drive multiple drive shafts 6 to rotate, that is, it can drive multiple grinding barrels 2 to rotate simultaneously. This application, by adopting a multi-station design, can process multiple gas storage cylinders in parallel, thereby accelerating the processing speed of the gas storage cylinders.

[0051] Meanwhile, the rotation time and speed of the grinding barrel 2 are set by the electrical embedded cabinet 3 to ensure that the surface of each gas storage cylinder is subjected to uniform force, so as to maintain the stability of mass production of the gas storage cylinder.

[0052] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
